IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. 172,229, dated January l1, 1876; application led November 27, 1875.

To all whom it may concern:

Be it known that I, FREDERICK B. WIGLE,

of Manslield, in the county of Richland and State of Ohio, have invented a new and valu able Improvement in Nut-Locks; and I do hereby declare that lthe following is a full, clear, and exact description ot' the construe4 tion and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1ot` the drawings is a representation of a side elevation ot' my nut-lock, and Fig. 2 is a horizontal sectional view thereof. Fig. 3 is a perspective detail view.

This invention has relation to means for locking nuts on rails where bolts and (ishplates are used at the joints of the rail-sections; and the nature otmy invention consists in a locking steel plate, which is adapted to receive the nuts after they are screwed home, and which is constructed with spring claspinglips, which, when the plate is forced to its place, will engage with the threads ot' some oi' the nuts and hold the plate rmly until spread apart by an instrument specially designed for the purpose, as will be understood from the following description: y

In the annexed drawings, A A designate two railroad-sections ofthe T shape, and B B are splici11gplates,which are applied to the webs of the rail-sections so as to cross the joint thereof. The plates B B are firmly clamped to the rail-sections by means ot' bolts a and nuts b. C designates a thin steel strip, which is nearly equal in length to the length of vthe fishplate on the nut side of the rail, and which has its edges bent in, as shown at e c, to prevent portions of the plate from getting in between the nuts and fish-plate. The plateGis punched to receive through it the nuts b. The holes may be rectangular or star-shaped. This perforated plate will prevent the nuts from turning. To prevent the locking-plate C from detachment lips g g are formed on it, the ends of which are notched and slotted. The notches f embrace the threaded ends ofthe bolts, and catch in the threads ot' these bolts. The slots it' are designed to receive the hooked ends ot' a spreading-tool, Gr, which is used, as shown in Fig. 2, for spreading apart the spring-lips g g, and detaching the locking-frame G from the nuts.

What I claim as new, and desire to secure by Letters Patent, is-

l. The notched spring-lips g g' on springplate C, for the purpose described.

2. The slots t' t' on lips g g, for receiving the hooked ends ofthe detaching-tool G, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

FREDERICK B. WIGLE.
